The original vi editor, updated to run on modern OSes

This is the original BSD ex/vi, updated to build and run on modern Unix systems. Compared to most of its many clones, the original vi is a rather small program ~120 KB code on i386 just with its extremely powerful editing interface, but lacking fancy features like multiple undo, multiple screens or syntax highlighting. In other words, it is a typical Unix program that does exactly what it should and nothing more. I intend to preserve this style in maintaining my port, except for changes to achieve POSIX.2 standards compliance, features in the SVR4 versions of vi, and, of course, bug fixes.
